Topic: Rigol DS2000 Hardware version 2.0 (Read 28991 times)

This is a DS2072 (or more a DS2202 now) with version 2.0 hardware.Looks like they are going to use the empty spot in the version 1 hardware to make a D model with Logic Analyzer included, and while they were designing the new pcb the input channels got reworked too. Unfortunately it doesn't look like something you can populate at home...

- Blue: Add, I do not know what is, but I have an idea (A kind of comparator / level translator or a simple digital buffer).

- There are also changes in the DC/DC power, it look better, but these changes will introduce less noise? What is behind, in the other side of the pcb? And I am not sure, but I think there are also changes in the PSU.

- To the input stage has been added a 50 ohm terminator (and other relay).

Wow, they had designed it before the 2012/10/29.LA connector is a PCI-E!

There are changes in the PSU to, but are minimal.I wonder what's behind the mainboard, but surely there are others eight channels for the LA, at least the traces from the connector to what looks like a comparator.

well, if 50R is only available in MSO, then it could make sense to hack that DSO to MSO (even with no FPGA populated) to get it enabled.

I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ... I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

Maybe, but the models are not on the market yet so there will be no firmware available, this one still runs on the hardware version 1 firmware. I wonder if you have the same non-functional 1M input button on that hardware...?

Yes, my HW version 1.0.1.0.0, is also fixed to 1M.

Now, this is my doubt: Anyone know how many versions of HW exist until today's date? And if this sequence of HW is correct (1.0 -> 1.0.1.0.0 -> 2.0), have the 1.0.1.0.0 version the internal 50 ohm termination too?

Okay I think I have the answer, just two HW version: 1.0.1.0.0 -> 2.0.And I have the feeling that in the 2.0 Ver. they have improved the PSU and DC/DC parts.

After reviewing the new main board for RIGOL DS2000 (HW Ver. 2.0). I think than this M.B is valid for, DS2000-S, DS2000-D, and then too for a possible DS2000-[DS or SD or ?] (ie whit LA and Function Gen.).

This is a comparison between the two hardware versions.Type of test: Noise floor. Results for hardware ver. 1.0.1.0.0:

(1):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.2. No probe connected in any channel and, only CH1 on.3. Setting: Full BW, Vector, 1mV/DIV (x1), DC, Adquire=Normal, Men.=Auto, Persistence=inf., Base time=500us, Trigger level=0V.4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.

(2):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.2. No probe connected in any channel and only CH1 on.3. Setting: Full BW, Vector, 1mV/DIV (x1), DC, Adquire=Normal, Men.=Auto, Persistence=inf., Base time=2ns, Trigger level=between 500uV and 600uV4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.

Hi all I also have attached 2 pics with the above setting on my DS2072 V2.0 Hardware.
